SPECIFICATION forming part of Letters Patent No. 604,773, dated May 31,1898. Application filed DeoemberZZ, 1897. Serial No. 663,014.. (Nomodel.)

To aZZ who/1t it may concern:

Be it known that I, DAVID 13. MILES,- a citizen of the United States,residing at Blackwater, in the county of Cooper and State of Missouri,have invented certain new and useful Improvements in Cultivators; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has relation to Cultivators.

The object of the invention isto provide a simple, durable, andinexpensive cultivator the cultivating-shovel of which may be easilyremoved for the purpose of repair and as easily fastened in place.

With this object in view the invention consists of certain features ofconstruction and combination of parts, which will be hereinafter fullydescribed and claimed.

In the accompanying drawings, Figure 1 is a perspective view of myimproved cultivator. Fig. 2 is a rear view and Fig. 3 is a sectional view.

In said drawings, 1 denotes the main frame of the cultivator, which ispreferably made of sheet-iron, the edges of which are bent and folded toform beam-supporting flanges a, Z), and c.

2 denotes the cultivator-beams,which snugly fit between the flanges a,b, and c, and are held in position by wedge-keys 3, that are driven downthrough alined perforations i in the flanges a and c. To prevent thesebeams from drawing out should the keys by any possible means becomeloosened, I provide the beams with stop-lugs at points immediately inadvance of each key, so that should the beams draw rearward the lugswill contact with the keys and prevent the beams entirely withdrawingfrom their position between the flanges.

6 denotes a rear brace provided with forked ends which embrace the rearends of the cultivator-beams,and 7 denotes the handle-stock, which hasone end fastened to the body of the cultivator and the other endprojecting inwardly.

8 denotes braces that are connected to the handle stock and have attheir lower ends holes 9, through which one of the forks of thebeam-brace projects. Nuts 10 are screwed u pen the ends of the forks andclamp the stockbraces and cultivator-beams in position.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of my inventionwill be readily understood without requiring an extended explanation.

The cultivator is strong and simple, and the parts are so assembled andconnected that while the cultivator-beams may be easily removed for thepurpose of repair or replacing them with new ones there is not theslightest possibility of their becoming accidentally detached.

Having thus described my-invention, what I claim, and desire to secureby Letters Patent, is-

1. In a cultivator, the combination with the main frame havinglongitudinal side flanges, of cultivator beams fitted between saidflanges, and means for holding said beams in place, substantially as setforth.

2. In a cultivator, the combination with the main frame having flangesa, b and c, of cultivator-beams fitted between said flanges,andwedge-keys for holding said beams in place, substantially as set forth.

3. In a cultivator, the combination with the main frame having flangesa, b and c, of cultivator-beams fitted between said flanges and providedwith stop lugs, of keys inserted through flanges a and 0 immediately atthe rear of the stop lugs, substantially as set forth.

4. In a cultivator, the combination with the metallic main frame bent atits sides to form flanges a, b and c,.the flanges a and 0 being providedwith alined perforations, of cultivator-beams fitted between saidflanges and provided with stop-lugs, and wedge-keys inserted through thealined perforations immediately at the rear of the stop-lugs,substantially as set forth.

5. A cultivator comprising in combination the following essentialelements, to wit: a metallic main frame, formed at the sides withflanges a, b and c, the flanges a and 0 having alined perforations,cultivator-beams fitted between said flanges and provided with stoplugs,wedge-keys inserted through said perforations immediately at the rear ofthe stopvator-beams and stock-braces to the beamlugs, a handle-stocksecured to the cultivatorbrace, substantially as set forth.
